My opinion of Twelve x Clara I think is basically that she was *definitely* in love with him, probably in a romantic sense. She WANTED that old man. The way she surged forward and kissed him on the cheek in the Christmas special felt way too much like she was working herself up to kiss him and just went for the safer route (I love that moment sm, they’re obsessed with each other I love it). The Doctor absolutely loves Clara, and we saw how far he would go for her. That’s the whole point of their time coming to an end. But (and this is just my feeling on it, I think headcanons where he also loves her romantically are totally valid and I love you guys for it) I personally don’t see him as being in love with her in the romantic/sexual capacity? They’re definitely a couple of freaks who are obsessed with each other and he wants to hold her between his hearts and keep her there forever. I think that part of this is also just because I believe that, from a little before he married River to the end of their marriage (and ofc he continues to love her afterward!) he loved her, and was pretty much dedicated to only being with her. I don’t see him having feelings for anyone else, and I think that during his marriage to River, she was the only person he was with, thought of himself with, etc. But I feel like so much of canon absolutely points to Clara having feels that are…well, how do I put this?
TL;DR
